8. That's what I was thinking

10. With smaller sub-groups within a poll there is a greater margin of error.

This is why the polling for hispanics and African Americans is frequently off. In the Survey USA poll of Ohio (O+3) they had Romney winning 22% of the black vote.

What happens is, say you have a poll of 100 people. In a group this size, maybe only 3 of them might be hispanic. If you happen to get one person who likes Romney..... BANG..... you have hispanics giving 33% of their vote to the GOP.

You have to be very careful when pulling out minority data from any poll.
